Dark Hair Dye and Chemical Relaxers Linked to Breast Cancer



The study of 4,285 African-American and white women was the first to find a significant increase in breast cancer risk among black women who used dark shades of hair dye and white women who used chemical relaxers.

Black women who reported using dark hair dye had a 51 percent increased risk of breast cancer compared to black women who did not, while white women who reported using chemical relaxers had a 74 percent increased risk of breast cancer, the study found.

The risk of breast cancer was even higher for white women who regularly dyed their hair dark shades and also used chemical relaxers, and it more than doubled for white dual users compared to white women who used neither dark dye nor chemical straighteners.

The association between relaxers and breast cancer in white women surprised lead author Adana Llanos, an epidemiologist at the Rutgers School of Public Health in Piscataway, New Jersey, although she worried enough about the safety of hair relaxers in African-American women like herself to stop using them years ago.
